[0027] The embodiment of the present application provides a hydraulic valve group debugging device, which effectively solves the problem of fixing the hydraulic valve group to one side of the testing device by rotating the threaded sleeve. When the hydraulic valve group is tested, the pressure difference inside the hydraulic valve is different, which will cause shaking at the interface of the hydraulic valve group, affecting the tightness of the connection. The tightness of the connection between the hydraulic valve joint and the interface is increased by extrusion, and then the L-shaped pull rod is moved to rotate the L-shaped pull rod at the side end of the flip plate, and the end of the L-shaped pull rod is inserted into the side end of the limit block. The top of the flip plate is pressed to rotate the flip plate around the connecting frame. The deflection of the flip plate drives the L-shaped pull rod to pull to one side, so that the two slides drive the arc-shaped clamping plates to squeeze each other, thereby increasing the stability of the hydraulic valve joint when in use and preventing the hydraulic valve joint from shaking.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that when the hydraulic valve group is fixed to one side of the test device by rotating the threaded sleeve, the pressure difference inside the hydraulic valve is different when the hydraulic valve group is tested, which will cause shaking at the interface of the hydraulic valve group and affect the tightness of the connection. The overall idea is as follows:

[0031] The sealing ring 16 fits with the inner wall of the interface 15, and the inner sides of the two arc-shaped clamping plates 17 fit with the outer surface of the hydraulic valve joint 12. A limit block 18 is fixedly installed on the outer side of each arc-shaped clamping plate 17. A connecting frame 19 is fixedly installed on the surface of each arc-shaped clamping plate 17 on one side. The connecting frame 19 and the limit block 18 are on the same horizontal line. A flip plate 21 is rotatably installed inside each connecting frame 19, and an L-shaped pull rod 14 is rotatably installed on the side end of each flip plate 21. By pulling the hydraulic valve joint 12, the hydraulic valve joint 12 drives the sealing ring 16 to leave the inside of the interface 15, and the hydraulic valve joint 12 can be quickly disassembled and installed, which is convenient for operation;

[0032] The end of the L-shaped pull rod 14 is engaged with the limit block 18, and the end of the flip plate 21 is connected to the connecting frame 19 through a fixed axis. At the same time, a positioning hole is opened at the side end of the flip plate 21. A fixed block 22 is fixedly installed on the side end of each slide 13, and a slider 24 is slidably installed inside each fixed block 22. The end of the slider 24 is engaged with the positioning hole at the side end of the flip plate 21. A telescopic rod 23 is fixedly installed on the top of each slider 24, and the top of the telescopic rod 23 is fixedly connected to the inside of the fixed block 22. An extrusion plate 25 is fixedly installed on the side end of each slide 13, and the slide 13 drives the extrusion plate 25 to move horizontally to apply pressure to the sealing ring 16.

[0033] Working principle:

[0034] In the first step, by moving the hydraulic valve group, one end of the hydraulic valve group is fixedly connected with a plurality of hydraulic valve joints 12, by moving the hydraulic valve joint 12, the sealing ring 16 on one side is driven by the hydraulic valve joint 12 to be inserted into the interior of the interface 15, so that the sealing ring 16 and the interface 15 fit each other, by moving the two slides 13, the slides 13 are driven to slide along the inside of the guide groove 11, the two slides 13 drive the arc clamping plates 17 to move, and the side ends of the two arc clamping plates 17 fit the surface of the hydraulic valve joint 12, and at the same time, in the process of moving the hydraulic valve joint 12, the hydraulic valve joint 12 drives the extrusion plate 25 to move and extrude the seal The surface of the ring 16 is used to squeeze the sealing ring 16. By squeezing, the tightness of the connection between the hydraulic valve connector 12 and the interface 15 is increased. Then, the L-shaped pull rod 14 is moved to rotate at the side end of the flip plate 21. The end of the L-shaped pull rod 14 is inserted into the side end of the limit block 18. By pressing the top of the flip plate 21, the flip plate 21 is rotated around the connecting frame 19. The deflection of the flip plate 21 drives the L-shaped pull rod 14 to pull to one side, so that the two slides 13 drive the arc-shaped clamping plates 17 to squeeze each other, thereby increasing the stability of the hydraulic valve connector 12 during use and preventing the hydraulic valve connector 12 from shaking.

[0035] In the second step, during the deflection process, the flip plate 21 squeezes the end of the slider 24, applies an upward thrust to the slider 24, and allows the slider 24 to squeeze the top of the telescopic rod 23, and the slider 24 slides into the interior of the fixed block 22. When the flip plate 21 rotates to a horizontal state, a reverse thrust is applied to the slider 24 through the telescopic rod 23, and the slider 24 is inserted into the positioning port at the top of the flip plate 21. Then, by pulling the top of the flip plate 21, the flip plate 21 is rotated at the side end of the connecting frame 19, and the connecting frame 19 deflects around the end. The flip plate 21 applies a thrust to the L-shaped pull rod 14, and the L-shaped pull rod 14 deflects with the flip plate 21, and the end of the L-shaped pull rod 14 leaves the inside of the limit block 18, releasing the mutual squeezing and fixing of the two arc-shaped clamping plates 17, and then moving the two slides 13 to slide along the guide groove 11 to separate the two slides 13, and pulling the hydraulic valve connector 12 to drive the sealing ring 16 to leave the inside of the interface 15, so that the hydraulic valve connector 12 can be quickly disassembled and installed, which is convenient for operation.
